About

VisuPhy develops interactive tools for exploring optics and laser physics. Every simulation runs directly in a web browser, with no installation or account required. The tools support learning, teaching, quick calculations, and early optical design work.

Contributing

Contributions to the physics, code, interface, documentation, and testing are welcome. Before starting a new simulation, please read the FAQ and contact visuphy@gmail.com to discuss its scope.

Licensing

Licensing is defined separately in each repository. Check its LICENSE file before using or redistributing the code.
